San Francisco Just Upzoned Half the City. The Outer Mission Got Room for One More House.

San Francisco's zoning map now allows buildings up to six or eight stories on transit and commercial streets across much of the west side. Richmond, Sunset, and Marina property owners went from a 50-year-old four-story ceiling to something much taller almost overnight. In the same round of planning documents that describe that shift, the entry for the Outer Mission is a single sentence: room for one more home near St. Mary's Playground.

That gap is not a rounding error. It is the story for anyone pricing a small apartment building in this neighborhood right now.

The Plan That Changed the West Side

San Francisco's Family Zoning Plan cleared the Board of Supervisors and was signed by Mayor Daniel Lurie on December 12, 2025, with the ordinances taking effect January 12, 2026. The plan was a response to a state mandate: California's latest Regional Housing Needs Allocation raised San Francisco's assigned housing target from 28,000 units to 82,000 units, and the city's own zoning fell roughly 36,000 units short of what the state required, even with a buffer built in. To close that gap, the Board rewrote height and density rules across the Richmond, Sunset, and Marina districts, along with other parts of the city's northern and western half, which had been downzoned since 1978 and had absorbed relatively little new construction while the eastern neighborhoods did most of the building.

Most rezoned streets went from a four-story cap to six or eight stories. A handful of corridors that were already zoned for height, including stretches of Geary Boulevard, Van Ness Avenue, and Market Street, were pushed even further, up to 14 or 65 stories in some spots.

Where the Lines Were Drawn

Districts 9, 10, and 11 were left out of that plan almost entirely. District 11, which covers Ocean View, Excelsior, and the Outer Mission, got what the city's own planning bulletin describes as minimal coverage: a strip along Ocean Avenue south toward Lakeview Avenue, and a corridor running east along Geneva Avenue toward the Balboa Park BART station and ending at Delano Avenue. Outside those specific stretches, the Family Zoning Plan simply does not touch the Outer Mission's residential blocks.

This wasn't an oversight. The plan's stated goal was to send new development toward parts of the city that had captured less growth since the 1970s, and it explicitly avoided neighborhoods the city classifies as priority equity areas, citing anti-displacement concerns. The three supervisors whose districts fall into that category, Jackie Fielder in District 9, Shamann Walton in District 10, and Chyanne Chen in District 11, voted against the Family Zoning Plan and later voted to condemn the state law that followed it, arguing it would encourage land speculation without guaranteeing affordability.

The Law That Was Supposed to Close the Gap

That state law is Senate Bill 79, the Abundant and Affordable Homes Near Transit Act, signed by Governor Newsom on October 10, 2025. Unlike the Family Zoning Plan, SB 79 isn't drawn along district lines. It applies to parcels within a half mile of a qualifying transit stop anywhere in an urban transit county, and San Francisco qualifies. On paper, that means the law reaches every neighborhood the Family Zoning Plan skipped, including the Outer Mission, since it sits near the Balboa Park BART station and several Muni Metro lines.

San Francisco chose to implement SB 79 through its own locally tailored alternative plan rather than accept the state's default zoning. Mayor Lurie signed the implementation ordinance on May 8, 2026, and the California Department of Housing and Community Development confirmed the plan met the law's requirements in a review letter dated July 1, 2026, the same day the law took effect statewide. Under that local plan, qualifying parcels near transit can get a density and height exception under a new Planning Code section, provided the city's existing zoning in that transit area already allows at least half of what SB 79's own default standards would permit.

Here is where the scale gap shows up. Planning documents covering the roughly 2,000 sites affected by this round of SB 79 changes call them modest, and the Outer Mission is the example they reach for. Reporting on the plan cites room for a single additional home near St. Mary's Playground as one of the Outer Mission's changes, while other sites in the same package, near the former Candlestick Park and at the corner of Cesar Chavez and Guerrero, gained room for 20 or more units.

What This Means If You're Pricing a Building Here

San Francisco's small multifamily market is not soft right now. The city's 2-4 unit apartment building segment posted its strongest quarter since spring 2022 in early 2026, and the broader multifamily market has been recovering along with it as rents climb and new construction stays limited. That backdrop makes it tempting to price every San Francisco submarket the same way: current rent roll, plus a premium for whatever the parcel might become if it were redeveloped under looser rules.

That premium is real in Richmond, Sunset, and Marina right now. A 2-4 unit building on a transit street in those neighborhoods sits on a lot that can legally hold three or four times as much housing as it could eighteen months ago, and buyers underwriting those deals are right to factor that into the offer.

An equivalent building in the Outer Mission mostly isn't sitting on that kind of lot, at least not yet. The neighborhood cleared both of the last two years' major upzoning efforts with barely any change to what most residential parcels can hold. Unless a specific property sits directly on one of the narrow corridors the Family Zoning Plan did touch, or on a parcel close enough to the Balboa Park BART station to qualify for the SB 79 density exception, the redevelopment story that's driving pricing elsewhere in the city doesn't apply here. Value in this neighborhood is still coming almost entirely from the income the building already produces.

That's not a knock on the Outer Mission as a place to own property. Rent growth citywide has been strong, and a building with stable, well-documented income doesn't need a speculative upzone story to make sense as an investment. It just means the two stories shouldn't be priced the same way. A buyer who applies a Sunset-style redevelopment premium to an Outer Mission parcel that never got the zoning change is paying for something the property doesn't actually have.

What to Check Before You Underwrite

The exceptions matter more than the rule here, because the changes that did happen are drawn parcel by parcel rather than neighborhood by neighborhood. Before you price a small apartment building in the Outer Mission, it's worth confirming three things directly: whether the specific parcel falls inside the narrow Family Zoning Plan corridor along Ocean Avenue or the Geneva Avenue-Balboa Park BART stretch, whether it sits within a half mile of a qualifying transit stop and could benefit from the SB 79 density exception under the city's Planning Code, and whether the current zoning designation on the property information map has actually changed or simply carried over. A building two blocks from St. Mary's Playground and a building on Geneva Avenue near the BART station can have very different answers to all three questions, even though both sit in the same neighborhood.

Getting that answer right before you write an offer, rather than after an appraiser flags it in escrow, is the difference between a deal that closes on schedule and one that gets renegotiated at the finish line.
